Ok.You have 24$. You used 20$. And you have $4 left. You bought 5 pens. So $20.00/ 5=$4.00. Each pen is four dollars.
Answer:
96
Step-by-step explanation:
First divide 360 by 2.
Then divide 180 by 5 and that is how many 5 pound bags he will use.
Then divide 180 again by 3 and that is how many 3 pound bags he will use.
1) b=1
-3+1=3b-5
Add 3b to both sides.
1=6b-5
Add 5 to both sides
6=6b
Divide both sides by 6
b=1
2) t=11
(1/2)t+7=(3/2)t-4
Subtract 1/2t from both sides.
7=t-4
Add 4 to both sides.
t=11
3) x=-0.878
-2.3 +1.2x=5.9-2.9x
Subtract 1.2x from both sides
-2.3=5.9-4.1x
Add 5.9 to both sides.
3.6=-4.1x
Divide by -4.1
x=-0.878
4)No solution
-7y-21=-3y-21
Add 3y to both sides.
-4y-21=-21
Add 21 to both sides
-4y=0
This is a straight angle. All angles add up to 180°.
We have been given angle MON = 41°
180° - 41° = 139°
Angle x = 139°
You do 6.394-3.200 which =
3.194
